Hi All,
 I have two selection boxes in a JSP . I pass values from one selectionbox to the other. Making the second one as the selectedBox.

when I try to retrieve the info in the servlet. I get only one value which is Highlighted.
Could someone let me know how to get all the values.

there are two ways of doing this... before submitting the form run through each of the options and select them OR
add it to querystring:

if #2
function validateForm(whichForm) {
      var qString="";
      var whichList = whichForm.selYOURSELECT; // *** MAKE SURE TO CHANGE TO THE NAME OF YOUR SELECT BOX
      for (i=0;i<whichList.options.length;i++) {
            qString += ((i==0) ? "?" : "&") + "enrollList=" + whichList.options[i].value;
      }
      newAction = new String(whichForm.action);
      ix = newAction.lastIndexOf("?enrollList");
      if (ix == -1) {
            whichForm.action = newAction + qString;
      } else {
            whichForm.action = newAction.substring(0, ix) + qString;
      }
      return true;
}

if #1:

function validateForm(whichForm) {
   var whichList = whichForm.selYOURSELECT; // *** MAKE SURE TO CHANGE TO THE NAME OF YOUR SELECT BOX
   for (i=0;i<whichList.options.length;i++) {
       whichList.options[i].selected = true;
   }
   return true;
}

call this the same way as above.
